How To Store Fondant Cutouts???

Help, I have 4 cakes to make all for the same party. One is going to be a tool box (found the inspiration on here, thanks) with tools out of fondant. My idea is just to lay or lean the tools around the box. Cake will be stored 2 days in fridge. Do I put the tools on when I frost (BC) or wait til day of party. Would really like to have it all said and done beforehand. Any advice would be appreciated since I am a newbie.

thanks for the advice. made a few of the tools this afternoon. looking pretty good for someone with no artistic ability. sometimes i get so excited about all of this, i can't sleep and my full time job is really cutting into my play time.
